摘要
传统的聚酯合成原料多为含苯环的化合物,以其制造的工程塑料不仅难降解,对环境危害大,而且对人类的身体健康也存在严重威胁。随着各国对环境保护要求力度的加大,传统的聚酯材料已难以满足社会发展的要求,寻找合适可替代型原料已成为当下研究的热点。由1,4-环己烷二甲酸二甲酯(DMCD)合成的聚酯不仅具有优异的性能,而且由于不含苯环,不会对环境造成污染,被广泛用于食品包装、儿童玩具制造等。1,4-环己烷二甲酸二甲酯(DMCD)的工业生产通常由对苯二甲酸二甲酯(DMT)催化加氢制得,其中选择合适的催化剂是反应的关键,目前催化剂的研究方向主要集中在Pd、Ru、Rh和Ni基催化剂。介绍了合成1,4-环己烷二甲酸二甲酯(DMCD)过程中多相催化剂的研究进展,系统地总结了催化剂的使用条件及其使用效果,为未来催化剂的研制点明方向。
Due to the harmful raw materials and difficulty of degradation, the engineering plastics produced by polyester would cause serious environmental problems and endanger the human health. Traditional polyester materials can not meet the increasingly stringent environment requirement. Therefore, we have to develop safe and environment-friendly alternative materials. The polyester synthesized using safe and green raw material ( dimethyl 1,4-cyclohexanedicarboxylate ( DMCD )) exhibiting excellent performance has been widely used in food packaging, children's toys, etc. DMCD is usually produced through catalytic hydrogenation of dimethyl terephthalate ( DMT) in industry. The key and difficulty point of this process are the development of catalysts with high performance. At present, Pd, Ru, Rh and Ni catalysts are the most reported catalysts used for hydrogenation of DMT to DMCD. In this work, the research progress on the development of DMT hydrogenation catalysts was introduced. The effect of catalysts and the reaction conditions of synthesis of DMCD were systematically summarized. This paper may provide a reference for design and development of high activity catalysts for DMCD synthesis.
